Embodiment

For the ease of it will be appreciated by those skilled in the art that the present invention is elaborated below in conjunction with accompanying drawing and embodiment.

As shown in Figure 1, disclosed connector integral body is the U type of traverse, and U type underarm is longer than upper arm.Said underarm is upwards bent inwards by the termination and forms arch support portion 10, and this arch support portion 10 is approximately isosceles triangle, and two waist angle portions are circular arc, avoid producing sharp scuffing; Arched upward by lower direction top and form the elastic joint part 20 corresponding with support portion 10 in the upper arm termination, elastic joint part 20 is provided with and is used for the convexity 21 that contacts with connected piece.During use, elastic joint part 20 is compressed, and the elasticity by the rear portion produces closely contacts with connected piece; Elastic joint part 20 will touch support portion 10 during by excess compression, produce support forces by support portion 10, thereby make elastic joint part 20 stop compression, avoid the excessive generation permanent deformation of pressure; When external force was cancelled, connector elastic joint part 20 arrived original state by spring return.

In addition, the terminal bending of the underarm back that forms support portion 10 becomes horizontal and does not contact the inboard of bending part with underarm, is beneficial to the firm support to elastic joint part 20.And in order to increase the elastic force between U type two arms, establish the arcuation kink 12 that arches upward and form above the lower direction in the nearly U type of U type underarm bending place, the upper arm middle part is established by the top and is recessed to form V-type kink 22 downwards.

Employing width embodiment illustrated in fig. 4 is that 2.0mm, thickness are beryllium copper nickel plating, the single face brush plating gold copper-base alloys of 0.1mm, and to its stiffened processing in advance.Tests such as the programming through computer coiling machine or multiaxis make-up machine, tool setting are bent into the connector shape with above-mentioned sheet metal at last, and the width of strip just equals the most wide degree of product in the future.After the connector bending, just cut off, continue the bending work of next connector, do not have the existence of waste material, all wastes only are to begin the accent machine to produce, so its stock utilization almost is 100%.During making, also can on strip, design raising and rise and cave in, or shapes such as design is cut off, torn, punching.

The key of this connector manufacture method is: 1) sheet metal, get the strip of same width, and to accomplish through bending, these bendings all along the vertical direction bending of strip length, can not have the bending of a plurality of directions.Because the manufacturing materials of connector is copper materials such as beryllium copper, titanium copper, high-conductivity copper alloy, super phosphor-copper for example; The lines texture is all arranged, and these lines textures have very big influence to metallicity, are in particular in that material is in the process of calendering attenuation; Toughness at draw direction is strong; Each item good mechanical properties such as elastic stress, in the horizontal toughness and other performance then toughness obviously descend easily fracture.Because the directivity of strip texture and the characteristic of five metals die stamping moulding, general connector are difficult to elastic stress direction and strip grain direction are consistent, in case and connector elastic force direction is consistent with grain direction, its each item reliability all will significantly increase.2) make by computer coiling machine or multiaxis make-up machine; Only need anchor clamps and tool on exploitation coiling machine or the multiaxis make-up machine; Carry out final punch forming without stamping machine; But can use stamping machine to carry out some in earlier stage prefabricated, as relatively to need the die sinking employing to be stamped to form connector, cost can reduce greatly.For instance; Adopt the method for the invention to make mobile phone connector, situation about changing for the height in space in the mobile phone is as long as regulate the support portion height at connector rear portion; Prolong the length of charging; Just can the connector shell foot partly be increased, need not drop into a large amount of money and carry out die sinking again, cost can be reduced to original 1/3.

According to statistics, end in May, 2011, Chinese cellphone subscriber surpasses 900,000,000; The annual whole nation produces the mobile phone total amount and reaches several hundred million ones; By using 6 connectors to calculate on average every mobile phone,, will save non-ferrous metal beallon tons up to a hundred every year if adopt the connector of this novel processing mode; The cost of aspects such as the manpower of its saving, transportation in addition, its economic benefit, social benefit can't be limited the quantity of.

Connector according to the invention and preparation method thereof is adaptable across expanding to automobile, household electrical appliances, communication product or the like field of electronics.

The preferred version that the foregoing description is realized for the present invention, and indefiniteness is exhaustive, the present invention can also have other variations under same idea.Need to prove that under the prerequisite that does not break away from the present invention's design, any conspicuous replacement is all within protection range of the present invention.
